Vatnajökull ice cave tours: the ice cap and its outlet glaciers

Vatnajökull is the largest ice cap in Europe and the source of almost every famous ice cave photograph taken in Iceland. This page is what the ice cap actually is, which of its outlet glaciers hold the caves, and which tour reaches which tongue of ice.

Quick answer

Vatnajökull covers roughly eight per cent of Iceland and feeds dozens of outlet glaciers that flow down towards the coast. The ice caves people book are in those outlets, not on the ice cap itself — chiefly in Breiðamerkurjökull, which calves into the Jökulsárlón lagoon, and in Falljökull and Svínafellsjökull above Skaftafell. Thirteen of the sixteen tours on this site go to Vatnajökull ice, from $100.

What an ice cap actually is

A dome of ice that makes its own weather

The caves are in the tongues, not on the dome. And the tongues are not interchangeable.

A glacier in a valley is a river of ice. An ice cap is a dome: snow accumulates on a high plateau faster than it melts, compresses into ice, and the whole mass spreads outwards under its own weight. Vatnajökull is that, on a scale that is hard to hold in your head from the road — it covers about eight per cent of the country and in places the ice is hundreds of metres thick.

What you actually see from the Ring Road are the outlet glaciers: tongues squeezing out between mountains and running down towards the sea. Those tongues are where everything happens. They are moving, cracking, melting at the front, and it is that movement and meltwater that make caves.

They also explain the black. Vatnajökull sits over an active volcanic zone, and ash from eruptions lands on the ice and is buried by the next snowfall. Cut down through the layers with meltwater and you get the black bands that run through the blue in every photograph from these caves.

One practical consequence: the tongues are all different. Breiðamerkurjökull ends in a lagoon and produces the clearest, bluest caves. Falljökull above Skaftafell is steeper, more broken, and is where the ice-climbing and crevasse tours go. The name “Vatnajökull” on a listing tells you the ice cap; the tongue tells you the day.

Thirteen of the sixteen tours here go to Vatnajökull ice. The three that do not are the Langjökull tunnel and the two Reykjavík departures that feed it.

The tongues

Which glacier each tour actually reaches

Four names cover almost everything on this site.

  • Breiðamerkurjökull

    The big one, and the reason Jökulsárlón exists: it calves directly into the lagoon. Most of the crystal cave tours from the lagoon car park go into this ice, including the one at $159 with 1,131 ratings and the dedicated Breiðamerkurjökull tour at $171.

  • Falljökull

    Steeper and more broken, above Skaftafell. This is where the crevasse walks and the more technical days happen, and it is the glacier on the small-group cave and hike tour at $152.

  • Svínafellsjökull

    The other Skaftafell tongue, and the one most people photograph from the car park without knowing its name. Blue ice walks here run most of the year.

  • The ice cap itself

    Nobody on this site sells a tour onto the plateau of Vatnajökull. It is a serious expedition environment rather than a day trip, and the ice there is not where the caves form.

The one thing on this site that is not Vatnajökull ice is a tunnel cut into a different ice cap entirely — and it is the only one open in July.

Common questions

Vatnajökull ice caves, answered

What is Vatnajökull?

Europe's largest ice cap, covering roughly eight per cent of Iceland in the south-east. Dozens of outlet glaciers flow down from it towards the coast, and the ice caves people book are inside those outlets.

Which glacier has the ice caves?

Chiefly Breiðamerkurjökull, which calves into the Jökulsárlón lagoon, and Falljökull and Svínafellsjökull above Skaftafell. All three are outlets of Vatnajökull.

Can you walk on Vatnajökull?

You can walk on its outlet glaciers with a guide, crampons and a rope — that is what the blue ice tours on this site are. Walking onto the ice cap itself is an expedition rather than a day trip.

Why is there black in the ice?

Volcanic ash. Vatnajökull sits over an active volcanic zone, ash lands on the ice and is buried by later snow, and meltwater cutting through those layers exposes them as bands.

How do I get to Vatnajökull?

The Ring Road runs along its southern edge. Skaftafell visitor centre is about 330 kilometres from Reykjavík and the Jökulsárlón lagoon about 380.

Which Vatnajökull tour should I book?

For a cave, the crystal cave tour from the lagoon at $159. For a walk on the ice, the Skaftafell blue ice tour at $100, which has the most reviews in this niche.
